Hi Pete.
yes, it looks that way but both images (2 different scopes) was focused by ASiair’s autofocus routine. Since each image was taken through a L-Enhance filter, where the bands are red(Ha) and Blue/green), and since the scopes are achromats, some CA is to be expected I suppose. So ASiair autofocus routine must prioritise one band over the other. Not much I can do about that I suppose.
